The graph below compares the motion of particles in two substances. one substance is a gas and the other is a solid.
particle motion
particle speed
substance
which statement best describes the two substances?
particles are closer together in solids so substance b is a solid.
particles are farther apart in solids so substance a is a solid
particles are farther apart in gases so substance b is a gas.
particles are closer together in gases so substance a is a gas

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

b. examine and describe cells

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
